' Application April 19, 1944; ser alNoiisnflfl t-claims. (01:128 -62) vThis invention relates to gummassager. An object of this invention is toprovide a gum .massager comprisinga casing adaptedto be held in the handand containiing aspring motor and. an offset flywheel adapted to berotated by the motor forvibrating the casing, and being further providedwith 'a manually; controlled brake to stop rotation of the fly wheel.

' Another object of this inventionis toprovide in a gum massageramassaging member remov-. ably mounted on the casing and adapted to,vibrate with the casing, said memberi being ad- .lfjustable on thecasing to various angular positions and carryinga gum massaging elementYet another object ofthis invention is to .pro-

vide [a 'compact,.-rug'ged and durable gum masbe practical and efficientto a high degree in. use.

'sager of the character described whichshall comprise few and simplepartsjwhich shall be-easy to assembleand manipulate, and which shall yetfiOthe'r objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements,

and arrangement ofpart's which will be exempli- 1. fied in theconstruction hereinafter described,

and of which the scope of application. will be indicated in thefollowing claims.

' designates a gum massager embodying the in- "ventionfi The samecomprises asplit casing H 'made'of moldedor, cast material suchas'plastic composition, or of any other suitable material.

The casing ll comprises hollow complementary parts l2 and I3 fittedtogether to form the casing. The parts l2 and 13 have contacting edgesl2a and 13a. Said parts are furthermore formed with neck portions [2band |3b respectively, together forming a neck opening l4 at one end ofthe casmg.

Extending fromthebottom ofthe part l3 are a plurality ofbosses I 6formed with internal threads l1. Extending downwardly from ,the top ofpart l2. are bosses l8alignedwith the bosses i6 and formed withcountersunk through openings l9.to

receive. fastening screws for fastening to- I get-her the-parts l2. and13 of the casing, The

bottom part I5 is Jfurthermoreformed -with four integral molded corner.supports 23 to hold in placethe' vibrating niechanism 25., Part I2 is,formed, with integral holders 26 to retain the mechanism on the cornersupports 23. Part I2 is furthermore formed with a through opening'3llfor the. purpose hereinafter, appearing, and it is also formed.witha notch 3| in the edge 12a thereoff, The.:use of. thenotch 3| willappear hereinafter;

, .At theinside ofthelneck opening l4 parts l2 .and' I3fa1fe'formedwithrecess grooves 36. Said grooves are formedwith flat surface 31. j

Thefvibrating mechanism 25 comprises a metal frame 40 having paralleltop and bottom walls 4| f and v4.2 respectively, interconnected byspacing bolts 43. Rotatably;mounted on walls 4| and 42 of frame40, areparallel shafts 45,46 and 41.

'Walls 4 and 42 are furthermore formed with aligned slots 48v for thepurpose hereinafter ap- .pearinglocated ,between shafts45, 46. On shaft4515 a gear 501'. Fixed totheshaft 45 is the innerend 51 of a spiralIcoil spring 52. The outer end of the coil spring is attached to one ofthe bolts 43 as shown at. 53.1 .The upperend of shaft 45 isfd'rmed withleft handed. threads 55 and screwed thereon is awinding stem 56 passingthrough opening- 30, in'part l2. Hinged to the outer end of, the stem 56is a wing handle 51.

' Mounted onand between the walls Hand 42 is a shaft GO having stems 61passing through the slots 48. The shaft thus hasIa slight floatingmovement or. play. .Onshaft 60 is a pinion or gear 63 meshing with gear50. The slots 48 are substantially tangent to a circle having its centerat shaft and aradius equivalent to the distance between shafts .45- and60, so that as shaft '60 floats-gear 63 .will always keep in engagementwith gear so. i v I v,Onshaft 60-.is .a's'ec'ondlarger gear 65. Shaft 46,is provided withapini'on 66 which meshes with the gear 65 inoneposition of the shaft 65 but which is disengaged from gear 65 inanother position of shaft 60. Thus when the spring is being wound shaftmoves to a position where gear and 68 will be disengaged, therebypermitting the spring to be wound without rotating shaft 46. However asgear 50 is rotated in an opposite directhe spring motor to rotate. the

tion when the spring motor unwinds, shaft 60 will be shifted to causeengagement between gear 65 and 66 for rotatingshaft 45.

On shaft 46 is a gear G'lmeshing with a gear 68 on shaft 41. On shaft 41is an enlargement for the purpose hereinafter appearing. Shaft 41furthermore carries an offset fly wheel 12. Thus when the springunwinds, the fly wheel rotates for vibrating the casing.

Brake means is provided to retain the shaft 41 against rotation. To thisend frame wall 4| is formed with a pair of slots 15. Attached to wall 4|is a brake spring 16. Spring 16 is provided with a pair of rivetedprongs 11 passing through slots for attaching spring 16 to Wall II. Thespring. 16 is disposed at right angles to plate 4i, and the free endthereof is adapted to contact the portion 10 of shaft 41. When thebrake'spring 76 contacts portion ID of shaft 41, rotationiof the flywheel is braked. Riveted to the outer end of the brake spring 76 is arod 8 0 passing through notch 3| in casin part [2. Upon pressing the rod8!] spring 16 is disengagedfrom shaft 41 to permit fly wheel and vibratethe casing, I

Mounted on the neck of thecasing is a metal sleeve 85 having flanges 86and 81 at the ends thereof. Flange 86 contacts theouter surface of theneck of the casing whereas flange 81 fits within groove 36. Flange 81 isfurthermore formed with flattened edges 81a contacting the flat portions31 of the grooves 36. Thesleeve 85 is thus prevented from rotatingwithin the casing. It Will be noted that the sleeve, 85 is assembledwith the casing parts and is held in place once the attaching screws aretightened. Mounted on sleeve 85 isa gum massager rod 90. Rod 90 isangularly shaped havihg an arm 9| and an arm 92 at right angles thereto.Screwed to one end of arm 9| is an adaptor 93 having a split stem 94frictionally fitted within the sleeve 85. Mounted on the outer end ofarm 92 is a massaging element ,95 made of rubber or the like material."Member '90 can readily be withdrawn from the casing by pulling thesplit stem 94 out of sleeve 85. Furthermore member 90 can be rotatedtoany desired angular position. It will now be understood, that when thefly wheel rotates the entire casing andmember 9D vibrate causing themassaging element 95 to massage the gums whenpressed'thereagainst.

-It will thus be seen thatthere is provided a device in which theseveral objects of this invention are achieved and which is. welladapted to meet the conditions of practical use; 7

As various possible embodiments might be made of the above invention;and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein ,set forth or shown intheyaccompanyingdraw- :ings is to be interpreted as illustrative and notin a limiting sense.
